UALCULATING Application filed February 29, 15535. eerie! Ho. 10,6130.

This invention relates to calculating machines and is illustrated as embodied in a machine of the type-shown, ior example, in United States Letters Patent No. 1,212,231,

granted Jan. 16, 1917, on application of Paul F. W. C. Krippendorf for calculating the areas oflotsoi shoe upper parts.

Machines of this type comprise a series of concentric pivoted disks so connected that the terminal disk of the series registers the total movement of all in efiecting a desired registration. The disks are also so connected that each drives the next so that the machine is set back to a zero position by manually turning the terminal disk hackward through the distance it has traveled in efiecting the registration.

in view of-the foregoing, it is an object of the present invention to provide improved mechanism applicable to a machine of the type referred to by meansof which the time and labor necessary to reset the machine after aregistering or similar operation will be minimized. To this end, the invention provides a power operated driving mechanism for a member such as a registering member to restore it to its zero position which is automatically rendered inoperative after the zero position has been reached preferably through an over-throwing movement between the above-mentioned registering member and an adjacent member. Conveniently, and in the disclosed machine, a plunger is provided, operated preferably by a cam, to effect the disconnection of the power drive from the registering member. As disclosed, the cam and plunger are mounted one in each of two adjacent members, and the cam is caused to move relatively to the plunger to move it by the overthrowing movement.

In accordance with another feature of the invention, asherein exemplified, the power driving member is resiliently and pivotally mounted for engagement and disengagement with the registering member, and a latch is provided, releasable by the operator, to efiect the engagement anu the means for antematically disconnecting the power driving member from the registering member eiiects a relatching of the power driving member out of engagement with the registering member.

These and other features of the invention comprising certain combinations and arrangements of parts will be understood from the following description of a preferred embodiment thereoi selected for purposes of illustration and shown in the accompanying drawings, in which,

The machine comprises a series of indicator or registration wheels or disks 10 mounted on a central axis 12 under a cap plate 14. The wheels increase rogressively in size from top to bottom, and are numbered inorder to correspond with the sizes and half sizes of shoes. Each wheel (Figs. 2, 3 and 4) has a lug 16 on its top surface and (except the lower wheel) a lug 18 on its bottom surface. The lugs on each two adjacent wheels interfere so as to limit relative movement of a lower wheel counter-clockwise on an upper one. The upper lug on the' upper wheel engages a lug (not shown) under the f the two terminal cap plate 14, in the same'way. It is clear that if the lower wheel'be rotated counterclockwise, it will pick up all the others in turn and wind up the series until the upper wheel locks against the cap plate, when no further movement will be possible.

Each wheel has on its periphery a series of pins 20, which are equally peripherally spaced on, all the wheels. Each wheel is normally locked against clockwise rotation relatively to the wheel above by a lever 22 mounted on the upper wheel and engaging a 7 pin on the lower. This lever can be raised by a spring-pressed finger piece 24 to release the pin and permit relative clockwise rotation of the lower wheel, A heavy coil spring .26 is attached to the axis 12 and to the lower wheel and tends to turn it clockwise. The

levers 22 all being in position, and the ma are so related to the areas of similar shoe pieces of successive half sizes that the slipping of a lever 22 from one pinto the next "will permit angular rotation of the corresponding wheel and all the wheels below it under the spring pull, down to the disk 28, pro ortioned to the area of that upper piece of 1; 1e size corresponding to the wheel. The wheel corresponding to the largest size 9 is at the top, $111068. certain peripheral movement of a smaller wheel will cause a greater I angular movement of that wheel and consequentlya greater movement of the counter wheel 30.

An order for a lot of Vamps, for example, is set up by slipping past the corresponding lever a number of pins on each wheel corresponding to the number of pairs required of the size corresponding to each wheel. The bottom disk 28 will add all the rotations corresponding to the items of the order and the tively to the axis 12 of the disk 28, the setresult will beindicated on a dial 3 2 operated by the shaft 32.

In order to make the readings of the dial show the actual areas involved, irrespective of the style and shoe part being considered, the wheel 30 is set in or. out radially relating depending upon the areal characteristics of the shoe partunder consideration. Forexample, the vam'psand quarters corresponding to a certain order will have different total areas, and difierent settings of the wheel 30 are necessary for them. The total area required is, however, for any type of shoe part, always defpendent in the same way upon the number 0 pairs and sizes desired, so that with the proper setting of the wheel 30, the areas corresponding to varying case lots of the same shoe part can be obtained accurately by suitable manipulation of the pins and levers and wheels corresponding to the size and pair data of the lots. .In'other words, the areas of a set of similar shoe parts Vamps, quarters,'or the like) throughout the range of sizes are always proportional to the same set of numbers, irrespective of style or type of shoe part, and these numbers are proportional to the diameters of the wheels 1 The shaft 32 is mounted in a carriage 36 which slides along ways 38 on the 'machine frame. The carriage is so constructed that the inner end of it carrying-the wheel 30 can be lifted slightly from the ways without losing the guiding relation, to bring the wheel 30 against'the disk28, and when it drops to the ways 38 it is out of contact with the disk an may be adjusted along the disk Without rubbing or .damage. A grasshopper spring 40 engages the carriage 36 and a down-turned terminal foot t6 (Fig. 5) which rests on the way 38. The lifting of the outer end oflthe lever by the spring 40 thus lifts the inner end of the carriage 36 and wheel'30; Depression of the lever by the operator drops the carriage. The lever can be held down by the latch 48 which engages the carriage -36. vThe lever 42.0211 ries two studs 50 which engage an inverted V-shaped protuberance 52 on' the shaft 32 when. the lever is depressed. The centering of this protuberance by the studs sets the indicator 34 on the shaft 32 to zero in case there has been any lost motion or slipping in the last-use of the machine, or in settting it back to the zero position, in which the lovers 22 all engage the left hand pins 20.

The setting mechanism for the wheel 30 will now be described. This mechanism comprises a graduated wheel 54: mounted to turn on a fixed stud 56 and connected by a metal 'band to the carriage 36 S0 that any movement of rotation imparted to the wheel 54 causes directly and positively a longitudinal movement of the carriage 36 upon its ways. The construction is as follows: 7

As shown, (Figs. 6 and '1) brackets 58 and 60 are rigidly secured to the frame work or a lever 42 pivoted at 44 on the carriage has base of the machine, and the latter is also rigidly connected to a radially disposed brace member 62 carrying the stud 56 which is held therein by a set screw 64. The stud 56 projects'upwardly through the bracket 58 and upon this stud the graduated wheel 54 is mounted to rotate. The wheel 54 is skeletonizedas shown in the drawings, and carries rigid therewith a segment 66. The carriage 36 has pivot-ally connected there band 70, preferably in one continuous piece as shown, is attached at one end 72 to the bar 68, passes thence along the segment 66, along the bar 74 pivoted at 76 to the wheel 54, thence around the hub of the wheel, along a second bar 78, pivoted at 7 6, thence along the segment 66 beneath the end 72 tothe opposite end of the bar 68 where it is made fast. A set screw 80 carried by a projection 82 bears against the centers of the band and secures it to the hub of the wheel, while other set screws'84 carried by the projections 86 bear against the pivoted arms 74 and 78, thus tighteningthe band and enabling a very delicate adjustment of the longitudinal position of the carriage 36 with respect to the wheel 54 to be made.

The wheel 54 is provided on its upper face and near its periphery with a series of graduations shown in that part of the apparatus now being described as running from 3 to 36, these numbers referring to the,

number of square feet required to cut 100 pairs ofa shoe part of the model size, a number found by experiment on that part. These graduations appear through an opening 89 in the base of the machine, as shown in Fig. 1. Whenthe number 16 appears in the opening 89, the wheel 54 will have moved the carriage 36 and wheel 30 so that 100 pairs of the model size of that part, when turned out by the proper wheel 10, will run up 16 square feet on the dial 34. v

A radial plate 88 is mounted to pivot or swing about the stud 56, but for the present will be regarded as fixed on the machine, and it carries at its forward edge a scale 90 which, in thecase of an apparatus such as that illustrated for use in connection with shoe parts, bears the designations of the different shoe widths and, as shown, running from AA to EE, the use of which will be described below. A fractional scale plate 92, graduated from 1 to 9, is connected to a segmental plate 94 by'a metal band 96 attached at its ends to the segmental plate 94 and passing around the hub 98 of the plate 92. There is also similar provision for the adjustment of the band to that described for the band 70. The segmental plate 94 rests and slides upon the radial plate 88 in a circular guide, and it carries rigidly connected therewith by the pins 55 a thin plate 100 containing an aperture of just suflicient size to allow the figures appearing upon the wheel 54 and fractional scale 92 to appear therethrough and indicate. the I from the axis 56 as indicated at 112, and a desired reading. The plate 100 partakes,

basis.

therefore, of any movement given to the segmental plate 94 butrthe aperture 89 in the base is made sufliciently large so that .whatever position the segmental plate 94 may take the reading through the aperture in the plate 100 will always be visible.

cry with a series of holes 102 spaced ,to cor- The wheel 54 is provided on its periphrespond with the numbers appearing on the face of the wheel and the segmental plate 94 carries a spring-pressed plunger 104 which locks the wheel and segmental plate together by entering one of the said holes 102. It,

will thus beseen that by withdrawing the plunger 104fthe carriage 36 is left free to beslid longitudinally until, throu h its connection with the wheel 54, the desired figure on the wheel 54 appears through the .aperture 100 when the plunger is allowed to spring in and lock the wheel 54 to the segmental plate 94. The fractional movement of the wheel 54 is secured by swinging the fractional scale plate 92 about its hub and thus through the metal band 96, moving relatively, to the radial plate 88 the segmental plate 94 which is now rigidly connected to the wheel 54 by the plunger 104, and the v fractional amount moved is indicated by the figure on the fractional scale plate 92 trated represent tenth parts of the graduations on the wheel 54.

So far nothin has been said about vary-.

ing widths of t e shoe parts whose areas are bein determined. The description so far has een' of'a machine for determining the areas ofa lot of shoe parts of the model width only, all the constants of the machine having been com uted on that Now the standard figure (read on the wheel 54) for 100 pairs of shoe parts is determined experimentally from the model size and width, and it is necessary, for the same reading in'the aperture 89, to secure different settings of the wheel 54 for the different WldtllS.- This is accomplished by moving the radial plate 88, which has heretofore been regarded as fixed, and is connected to the wheel 54 through the parts 110, 108, 106, as, 96, 94,104, 102 in order. The mechanism for shiftin this whole system for widths will now be described.

The brace member 62 is slotted radially the graduations on the scale plate 92 and in the construction illusblock 114 is mounted to slide in said slot and carries rigidly connected therewith and extending vertically upward a post 116 entering a cam groove 118 in the lower face of the wheel 54. This cam groove extends in a course progressively diverging from the axis of the wheel 54. An auxiliary radial plate 120 slides at its forward end upon the bracket 60 and is pivoted between the said bracket and the stud 56 to the radial plate 88 by means oi an annular flange 122 (Fig. '9) extending into a cone s ending annular groove in the plate 88.

his auxiliary radial plate 120 has "formed therein a radial slot 124 through which the post 116 passes and whch fits the post, while the radial plate 88 is entirely cut away in the vicinity of the post 116 "as shown at 125 so as not'to contact therewith at any time. The plate 88 rests near its forward end upon the hits 126 and the two are secured together y a spring-pressed plunger 126. (Fig. 9) sliding in the plate 120 and entering one of a series of holes 128 (Fig. 6) in the depending segmental flange 130 of the plate 88.

Any relative adjustment of the plates 88 and 120 by the plunger 126 turns the plate 88 bodily about the axis 56, because of the fixed location of the post 116 in the slot 124,

- and the holes 128 are so spaced that by moving the plunger 126 from one to the next, as indicated by the pointer 132 on the plate 120 and-the scale 96 on the plate 88, the wheel 54 will be shifted with the plate 88 just enough to compensate for the percentage excess in area of shoe arts of one width over those of another. e cam groove 118 is so formed as to effect the proper compensation for the particular standard number appearing in the aperture 79 by a proper adjustment of the post 116 along the slot 112.

111 using the machine the operator will set up in the aperture 89-106 the standard number, found by experiment, representing the area of 100 pairs of the shoe part he is interested in, of model size and width by means of the plungers 104 and 168, and will put the plunger 126 into the desired hole 128. He will then run 06 on the wheels 16 the numloer of pairs of the size corresponding to each wheel by letting that nuinher of pins slip loythe corresponding locking lever. The disk 28 turns under the tension of the spring 26, with the release of each lever, and the total area adds up on the wheel and is registered.

lriorto the present invention the operator has heen obliged to wind the machine up again against the spring 26 by handto set it hack to zero. rlutoinatic mechanical means for shooting this operation will now be described.

Pivoted at 133 to a bracket 182 on the main frame 134 is a vertical standard 136.

nevasee A. motor 138 is mounted on the bracket 132 and is belted to a shaft 140 which drives, by

worm gearing 142, a shaft 144 in the stand?" ard 186, and on the upper end of this shait is mounted a friction wheel 146 faced, in the illustrated machine, w1th a well-known composition material lrnown. in the trade as Uskide. The standard 136 tits slidably in The standard 136 is latched agamst swinging out by a latch154 (Figs. 16-14) pivotally mounted on the housing 148 at 156, and having a hackwardly extending tail 158 which normally rests in a notch 160 in a dog 162 pivoted at 164 to an arm 166 last on a rockshaft 168 which may he rocked by a finger lever 170 (Figs. 1 and 5). When so rocked it lifts the dog 162 against the stud 172 which contacts with a beveled surface 174 (Fig; 13) on its upper end. This operation lifts the tail 158 of the latch 154 and unhooks it from the standard, which is then pushed out by a spring plunger 17 6 and the dog 162 also rotates suificiently to unhook itself from thetail 158 just after the unlatching. Pins 178, 180 mounted on the latch 154 and the dog 162 carry a little double hook 182 pulled down by a spring 184. This double hook pulls the latch 154 and the dog 162 back into operative position when the standard is thrown back into the housing and the finger lever 170 is released. It should be noticed that the latch 154 returns to operative position when the standard goes hack, whether or not the finger lever 170 has been released. Whenever the dog 162 drops, a hevel at the bottom of its notch 166 enables it to latch over the tail 158 whether this happens hefore or alt-er the relatching.

The automatic mechanism for throwing the standard heel; will now he described. The second lowest wheel of the series 10, (now numhered 186 Fig. 2), has its lower dog 18 mounted on the bottom of a plate 188 (Fine. 2 and 5) pivoted on the shaft 12 and hel' in a normal position by two opposed springs 186, 182 and a flange 194 resting against a'spoke 186 of the wheel 186. When tha motor winds up the machine, the lower wheel can therefore overthrow until the flange 194 strikes the spoke 188.

Pivoted on the lower wheel 152, at 266, is an arm 264- having pivoted at its end 262, a rod 265 arranged to slide through a hole in the rim of the wheel 152. The-pivot 202 is extended upwardly in a cam roll which rides in a cam slot 266 in the rim of the wheel 186. The machine in the position shown in Fig. 5 has-just reached the zero position, with the 1,eva,ssa

wheel146-still running on the rim 150. Further movement of the wheel 152 will move the cam roll 202 to the out-lying upper end of the track 206, as seen in Fig. 5, which will force out the pin 205. When the wheel 152 has turned enough the pin 205 strikes a contact plate 208 on the standard 136 and forces it back into latched and inoperative position. The wheel 146 having thus ceased to drive the rim 150, the spring 190 pulls back the plate 188, wheel 152, and rod 205, to the Fig. 5 position, and the machine is ready for a new operation.

As seen from Fig. 1, the machine is a twin so that two sets of shoe parts can be totaled simultaneously. The two machines diiier only in the proportion of their parts, one being adapted for small shoe parts and the other for large ones.
